At the current June reading, Zillow ZORI was $3,546, 3.1% above a year earlier. In named wider context, the City of Boston context rent was about $3,469, the Suffolk County context rent was $3,423, and the Boston-Cambridge-Newton, MA-NH metro context rent was $3,210. This places the ZIP index above each broad comparator, although none is a ZIP substitute. ZORI is a typical observed asking-rent index at ZIP scope, blended across rental types; it is not a signed-lease series and does not report a specific unit's rent. The five-digit label 02119 is both a Zillow ZIP market identifier and a Census ZCTA match. A ZCTA is a statistical area, not identical to a USPS delivery ZIP.
Those separate geographies are not the only source distinction. In the matched ZCTA, ACS 2024 five-year data put median gross rent at $1,329 for occupied renter homes. That survey measure includes selected utilities, unlike an asking-rent index, and its respondent and occupancy universe differs from current marketed supply. HUD's FY2026 two-bedroom FMR is $2,311: an administrative, bedroom-specific standard rather than asking rent. The bedroom figures here are modelled estimates, never measured bedroom rents: scaling ZIP ZORI by the local HUD ladder produces monthly estimates of $2,503, $2,702, $3,546, $4,433, and $4,695 from studio through four bedrooms. The ladder preserves local HUD relative sizing; it does not convert HUD standards into lease comparables.
History supplies the key counterweight to a single current asking-rent snapshot. Same-month annualized ZORI change was 3.1% over 1 year, 4.0% over 3 years, and 7.7% over 5 years. Rent therefore remained higher than a year earlier, but the newest pace breaks from, rather than confirms, the stronger longer-period growth path. These are backward-looking measurements, not forecasts or investment recommendations. The series has complete 100% coverage. Its annualized monthly-return variability of 5.2% is consistent with the supplied high-variability label, so a reader should place less confidence in any one current index value than in the broad historical direction. Separately, the maximum peak-to-trough drawdown reached −5.7%, documenting a prior decline within the observed path. Transparent national discovery ranks among history-eligible ZIPs were 765 for momentum, 2,844 for stability, and 1,821 for balanced performance; lower ranks place higher and none forecasts rent.
Income and burden data sharpen the mismatch but must remain within the ACS survey universe. The ZCTA's median household income was $48,488, versus an arithmetic required-income screen of $141,840 to place the current monthly ZORI at 30% of gross income. This is a budgeting arithmetic comparison only, not advice and not an applicant qualification rule. ACS also counted 8,756 renter-occupied homes, of which 4,997, or 57.1%, reported gross-rent burdens at or above the same threshold. These are estimates from a five-year survey of occupied renter homes, not proof that a particular available unit is burdened, or that an individual household can or cannot meet a rent.
The stock composition sets scope without revealing a particular listing. The matched ZCTA contained 13,023 housing units, including 3,085 single-family units and 2,584 units in large multifamily structures. Renters represented 73.5% of occupied homes, while the total housing vacancy rate was 8.5%. That renter presence frames the relevance of rental measures, but aggregate vacancy does not demonstrate availability, condition, or pricing for any named address. Likewise, the survey's structural categories do not identify the mix of currently advertised unit sizes, so they cannot validate the modelled bedroom ladder or a current ZORI quote.
Resale evidence introduces a different tension. In Redfin's direct rolling-three-month ZIP for-sale observation, median sold price was $659,851, up 5.6% year over year; 23 homes sold with a median 26 days on market. There were 87 active listings, while reported inventory was 41 homes, equal to 5.5 months of supply. Sale-to-list signals were an average 100.48% and a 36.4% sold-above-list share. This is for-sale liquidity and pricing evidence, not rental transactions or rental comparables. Against the income screen's large gap and the history slowdown, the resale price change exceeding current asking-rent growth challenges a simple reading that the latest rent movement alone summarizes every housing-market signal.
Dividing annualized ZIP ZORI by the Redfin median sold price produces a 6.4% cross-source screening ratio. It is only a screen: it is not a cap rate, property yield, net return, expected return, or an estimate of property economics. The numerator is a blended asking-rent index and the denominator is a median of observed ZIP sales, so neither necessarily represents the same building, transaction date, unit type, operating cost, or owner result. Read beside the income screen and history slowdown, the ratio identifies a comparison worth inspecting rather than resolving the rent-versus-price tension.
Several limits remain before interpreting any individual property. The ZCTA and ZIP label alignment does not make their populations identical, ACS survey estimates have margins of error, and the public measures describe aggregates rather than a listed home. A property-level review would need the advertised rent date, bedroom configuration, utilities included, lease term, concessions, and whether the unit's condition and availability match the index universe. For a resale comparison, the property type, sale date, list price, and sale record would also need confirmation. What specific listing terms actually match the rent index, the modelled ladder, and the for-sale observation being compared?
